JULIAN DEMATTEIS, OF BATAVIA, IOWA.

FLOOR SCRUBBING AND POLI$HING MACHINE Specification of Letters Patent.

Application filed February 10, 1912. l Serial No. 676,809.`

To all whom 'it may concern: Y

Be it known that I, JULiAN DEMATTEIS, residing at Batavia, in the county of Jefferson and State of Iowa, have invented a new and Improved Floor Serubbing and Polishing yMachine, of which the following is a specification.

This invention relates to improvements in that class of floor scrubbing machines in the construction of which is included a fluid holding chamber and valve controlled means for feeding-the fluid to the scrubbing and polishing elementsas desired. y

My present invention seeks to provide an improved scrubbing'and polishing means of the general character stated, in which the parts are especially so designed and cooperatively arranged whereby the manufacture thereof is economically effected, and the said parts compactly and simply arranged so the use of the machine is easily under stood and convenient for the operator.

lith other objects in view, thatgwill hereinafter appear, my present invention in its generic nature, embodies an improved ar rangement of the brushinor and )olishine' t: b D

rollers and means controlledi'by certain manipulations of the handle or pushing lever of the machine, for providing a substantially continuous reuse of the ,scrubbing fluid and under a-mi-niinum Waste thereof.

In itsA more complete nature, my present invention includes'an improved means for adj usting the fioor pressure of the scrubbing and polishing rollers, means operable byl certain manipulations of the pushingA lever or handle of the machine for effecting a rise of the said polishing and scrubbing rollers to provide for the maximum spread of the water when let out of the fiuid chamber to the said rollers.

In its more subordinate features mypresent invention consists of the peculiar and novel combinations and arrangement of the parts hereinafter fully explained, specifiand illustratedin the accompanying drawings, in which i -Figure 1 is a perspective view of my floor scrubbing andv polishing machine. F ig. 2 is. a

Fig. 14, a detail section thereofon the line 14-14 on Fig. 13, yand Fig. 15 is a detail view of the lifting lever device hereinafter specifically referred to.

' In carrying out my present invention, the main or body portion of the machine is preferably made offstiff sheet metal, of the general shape shown in Figs. 1 and 2 of the drawings, and the said body comprises an outer casing' or shell consisting ofthe sides a., rounded ends b, and a top c, the latter having a central opening Z that receives a filling tube 3, presently again lreferred to.

2 designates rubber tired carrier wheels of which there are two at each side, and they are mounted upon steel'stub shafts 50 riveted or otherwise made fast-to the plates 21, secured upon the side of the casing. Thecarrier wheels 2 at one or both sides of the machine, each have an internal gear 43, that meshes with and imparts motion to each of' the pinions 28 fixedly held on the stub ends 45 that form parts of the hollow steel shafts 44, on which the hubs 29 of the polishing roller and the scrubbing cylinder are mounted, as best shown in Figs. 1.1 and 12 ofthe drawings.I At each end ofthe casing is located a pocket or pan 42|, and these alter.- natelycatch the dirty Water from theV rollers as the sameis' carried up bythe similarly moving rollers 24.-25.

12 'designates a horizontal division vplate length and ,which'willfpresently appear. Bar 7 has'.

slide way7c on itsunder side extending its in this slideway is mounted a slide valve 40 having a series of holes 40a, adaptedto be moved into and out of register with the discharging outlets 7a in the bar 7.

' y Sldesignates a bifurcated head block made fastto the side valve 40, the which passes'through the said shank of slide valve Y and has movement in the elongated slot 7b in the bar 7, see Fi'g.'7. iShank 35a has a stop collar 35h, which extends below the slide valve 40 and carriesva screw nut 38, presently again referred to.

VFor shifting the slide valve 40 tov either open or close, the discharging apertures in the bar 7, either of the two ways shown in the drawings may be used but, I prefer to construct each machine with the two means shown since it provides for conveniently concrank lever,

I tank, both of trolling the shifting of the slide valve 40 by either the hand or foot action of the operator.

Referring now more particularly touFigs.' 2 and 7 of the drawings, 34 designates a bell the shifting of which not alone atuates the slide valve `7, but also the valves that control the discharges from the dirty water pockets, hereinafter fully explained. Lever 34, is pivotally mounted in a bracket 53 on the inside ofthe filling tube, and it has its long or pendent member 34apivotally connected to the head block The othe'r member of the lever34 has a pair of laterally projected lugs 34e-434', and a third laterally projected lug 34d, the latter engaging a stout leafv spring 37 mounted in the filling tube, and which normally swings the lever 34 to shift the valve'40 to close olif the discharges from the main tank.

In the drawings two ways are shown for depressing the bell crank lever 34 to shift valve 40 to open the discharges from the which engage with the upper one of the lateral lugs 34. One of the lever depressing devices, consists of an eccentric cam 33 rotatable with a shaft 17 mounted in bearings 17a, of a yoke holding frame 10, preferably cast integral or otherwise made solid with the feeding, tube 3, asis clearly shown in Fig. 7.

11 designates a yoke frame, the ends IIL- 11L of whichvengage the squared ends of the shaft 17, and are clamped theregn by the nuts 18. n'

designates a wooden handle that fits ra soclget 11b in the yoke 11 as shown.

By reason of arranging the yoke and handle and providing the shaft with the eccenvalve l40 to the levers 5 as receivin `swings the bell crank lever against the tension of the spring 37, and thereby shifts the v for a clean water discharge between the pol- `1shing rand scrubbing rollers, .it being obvious that as the handle is swung back again,

the spring 37 shifts the lever 34 to close the valve 40.

54 vdesignates a. pusher or guide bolt mounted in the lateral lugs of the lever 34, and it carries an, adjustable head 32 that normally projects in a plane above the top of the feed tube 3.

3a designates a cover plate for the port `3 that is hinged to swing 'in the horizontal plane. Cover 3a has a convexed seat 30 to fit over-the pin head 32 when the said cover is closed. Head 32is rounded so' that the cover 3x1 in closing, depresses the pin and shifts the lever 34 to open thevvalve 40. By providing the coyer 3a, the same can be easily shifted to the open or closed position by the foot of 'the operator, engaging with the cover eX- tension 30a.

Referring now to the pockets for holding the dirty water, it should be here stated, that in mv machine I provide for the reuse' of the dirty water with each fresh supply of clean water, providing, as it were, a fountain action, 'since the reuse of the dirty Water is kept up until'all of the clean water is out of the main reservoir, after which the Inachine is conveyed to a suitable point for emptyingthe dirty water and for relling with clean water. y

Each of the-pockets 42 hasanose portion 42a that extends closely to the rollers so as to alternately catch and in a measure scrape off the water carried' up and over'by the rollers, see full arrows y and dotted arrows the opening position, to allow 5, arranged as diagrammatically shown in Fig. 8, and as shown in detail in Figs. 2 and 7 ,`which show the inner slotted ends 50 of the lower extension of the shank of the sli ing block 35, and in such a manner that when the bell crank lever v 34 is shifted to open the slide valve 40',the 'levers 5 and the valves 31 are swung to the dot and dash positions shown in Flg. 8.

To provide for conveniently adjusting` the pressure of the scrubbing and the polishing rollers `S24-25, their stub shaft 'portions 45 move in the .cut out portions p-p of the sides of the casing, see,Fig. 3,` and are journaled on the pendent arms of bell crank levers G -fulc'rumed on the stub axles on which the carrier Wheels are journaled.

The long arms G1 of each setl of levers G extend toward each other and terminate in slotted heads 62 that lap and receive the shank 47a, of a nut 47, that receives the threaded shank 27, of an adjusting member, the lower end of which has a stepped bearing in the lug 4S on the casing, and Whose upper end extends through and above the yoke trame member l0, and terminates in a milled head S). A coiled spring 2G is mounted on the shank 27 and normally holdsl the rollers` 25, 2% against the door, it being understood thatby adjusting vthe screw shanks 27, the nuts t? will travel up or down and regulate the degree of pressure of the said rollers 24tand 25.

ln Figs. 13, 14 and l5, I have shown a somewhat modified construction of the rolladjusting means, and in this form in addition to the adjusting devices shown in Figs. 3 and T, means are included for bodily raising the rollers ott the floor irrespective of their degree oit' pressure adjustments, Whenever the Water is discharged from the reservoir and the end pockets, so as to give the' Said Water free flow over that part of the floor being worked. lFor such purpose a lifter device is used with each listing shank, as shown in detail inr Fie. 15, the same consisting of an apertured body 91 rockahly mounted in a bracket l0 on the plate 10, a toe port-ion 92 slotted for fitting on the shank under the head S) and a heel Sli-l that 'projects in the path of an eccentric cam 94, on the handle yoke member ll, which engages and depresses the heel Q3, when the. handle is swung for Yardly to open the slide valve e() and valves 31, and thereby lift the Shanks QT againstthe tension of the springs 2G, and in consequence swing the crank.

levers 6 to raise the rollers ott' the floor.
